Thanks @hube2 but to be honest that code is not doing anything in my end :S
Sorry for being asking the same thing in 2 threads, I thought this was not being watched anymore.
But @hopkirk described this problem very eloquently, the fact of the matter if it is currently impossible to remove images from a gallery in a front end form.
I described the specific problem in this thread

Thanks!
